Abraham Lincoln- preserved the union
Ronald Regan - trickledown economics
Theodore Roosevelt- built Panama Canal
George Washington - commanded continental army
Franklin D Roosevelt - new deal program
Thomas Jefferson - Louisiana Purchase
Andrew Jackson - expanded presidency
John Marshall - Marbury v Madison
I believe it is A, because of the education that could now be explored at universities.
